"Attempted to read or write protected memory" exception in v2.1.0

[Gusi]

The following code was working fine in previous releases (last tested v2.0.7) but in v2.1.0 is throwing: $exception {"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."} System.AccessViolationException HResult -2147467261 int

public static IList<T> SqlQuery<T>(this DbContext db, string sql, params object[] parameters) where T : class
{
    using (var db2 = new ContextForQueryType<T>(db.Database.GetDbConnection()))
    {
        var ret = db2.Set<T>().FromSqlRaw(sql, parameters);
        return ret.ToList(); // EXCEPTION HERE
    }
}

private class ContextForQueryType<T> : DbContext where T : class
{
    private readonly DbConnection connection;

    public ContextForQueryType(DbConnection connection)
    {
        this.connection = connection;
    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlite(connection);// options => options.);
        base.OnConfiguring(optionsBuilder);
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<T>().HasNoKey();
        base.OnModelCreating(modelBuilder);
    }
}

I'm not sure if this will be enough to catch the bug, so please ask me for more details if needed. Currently using packages SQLitePCLRaw.core and SQLitePCLRaw.provider.sqlite3.

Yeah I'll probably need more info. Can you post a minimal repro project?

Fixed in v2.1.1 Thanks!
